RENEWABLE FLANGE FOR CAR-WHEELS.

To all whom it may concern Be it known that I, FREDRIOK W. J OHAN- SEN, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Renewable Flanges for Car-WVheels, of which the following is a specification.

This invention relates to a renewable flange for car wheels.

The object of this invention is to provide a facing or supplementary wearing flange for car wheels, which is so constructed that it may be detached and renewed before the main wheel flange is exposed to wear.

A further object of the invention is generally to improve the wheel, so as to increase its utility, durability and general efficiency.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a side elevation of the wheel, showing the application of the invention. Fig. 2 is an enlarged cross section of same, partly broken away.

Referring to the accompanying drawings, A indicates the hub, B the plate, C the tread, and 2 the wheel flange which is here shown as especially designed for the purpose of receiving a supplementary wearing flange 3. The wheel proper may, in this case, be cast of a cheaper grade of material, as cast-iron, while the wearing flange 2 is preferably drop forged, or otherwise formed of a higher grade material as steel, and may be secured to the main flange of the wheel by suitable means, as by the rivets i.

For the purpose of relieving the securing bolts of the peripheral frictional strain or pull caused by the friction between the flange and rail, I have provided a series of segmental projections 5 on the main flange, and corresponding pockets 6 on the wearing flange, so positioned as to interlock with the projections on the main flange. This Specification of Letters Patent.

Application filed November 16, 1912, Serial No. 731,745. Renewed December 15, 1913. Serial No. 806,912.

construction prevents any tendency of play between the flanges, and consequently relieves the securing bolts of any unnecessary strain.

The flange 3 may be removed at any time when it is worn to such an extent as to eX pose the main cast flange 2 of the wheel, and may be replaced by a new flange, thus increasing the life and eiiiciency of the wheel almost indefinitely, as there is very little wear on the tread portion of the wheel.

I wish it understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of theappended claims, and that I do not wish to limit myself to the specific design and construction here shown.

Having thus described my invention,what I claim and desire to secure by Letters Patent, is-

1. A renewable wearing flange for car wheels comprising an annular wearing flange, means for securing the flange to the main flange of the wheel, and means for relieving the securing means of lateral shearing strain, said means also preventing peripheral movement between the wearing flange and main flange.

2. A renewable wearing plate for car wheels, comprising an annular wearing plate, means for securing the plate to the main flange of the wheel, and means for preventing peripheral movement between the wearing plate and the main flange.

3. A renewable wearing flange for car wheels, comprising an annular wearing flange, means for securing the flange to the main flange of the wheel, projections on the main flange, and pockets on the wearing flange so positioned as to interlock with the projections on the main flange.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witn esses.
